Watchdog Timer for RPi series



The procedure referenced here is still valid for ResinOS 2.x?

Are there any issues associated with enabling the WDT (WatchDog Timer) on current versions running on the RaspberryPi (3 or Zero)?
Is there any specific recommendation regarding the timeout lenght?

I had one instance were a PI crashed (offline on the dashboard) after a really long (months) uptime. The activity LED was blinking in a pattern (5 short blinks). It worked ok after a power-cycle. Will the WDT help prevent similar failures?
